Title: Method of forming capacitive insulating film
Inventor: YOSHIIE MASANOBU
IPC: H01L27/04
Filed: 1988-10-17
Abstract: PURPOSE:To form a capacitance section having a capacitance value of approximately 50Angstrom  in conversion to a silicon oxide film by shaping a silicon nitride film in specified thickness through a vapor growth method and thermally treating the silicon nitride film within a predetermined temperature range through a lamp heating method in an atmosphere containing ammonia or nitrogen. CONSTITUTION:A silicon oxide film 5 in 30-100Angstrom  is formed onto polysilicon 3 through a thermal oxidation method, etc., and a silicon nitride film 6 in 30-100Angstrom  is shaped through a vapor growth method from silane and ammonia. The silicon nitride film 6 is thermally treated for several sec or several hundred sec within a temperature range of 900-1200 deg.C through a lamp heating method in an atmosphere including ammonia or nitrogen. Heat treatment enables pinholes in the silicon nitride film to be removed, thus preventing the increase of leakage currents. Polysilicon 7 for the upper electrode of capacitance is formed in approximately 500-4000Angstrom . A photo-resist 42 is shaped selectively onto polysilicon 7, and the polysilicon 7 is etched while using the photo-resist 4 as a mask. The PR 42 is removed, and the capacitance can be formed.

Title: Optical semiconductor device
Inventor: SUZUKI SHINICHI
IPC: H01L31/12
Filed: 1994-10-26
Abstract: PURPOSE: To obtain an optical semiconductor device where light from a light emitting element can be received by a photodetector by detachably mounting a forming body where the light emitting element, the photodetector, and a substrate are formed in one piece at a housing body. CONSTITUTION: Illumination light from a light emitting element 4 of a photo interrupter passes through a cavity part 9, is reflected by a reflection part 12, is radiated from a hole 10, passes through a groove part 8, and then enters a hole 11. Then, it is continuously reflected by a reflection part 13 again, passes through the cavity part 9, and is positively applied to a photodetector 5. Then, since a forming body 1 where the light-emitting element 4, the photodetector 5, and the substrate 3 are formed in one piece is detachably mounted to the housing body 2, the position of the light emitting element 4 for the reflection part 12 of the housing body 2 and the position of the photodetector 5 for the reflection part 13 can be freely adjusted.  Therefore, the forming body 1 can be mounted to the housing body 2 at a position where light from the light emitting element 4 can be most efficiently received by the photodetector 5, thus achieving a long-term use and extremely reducing the troublesome operation such as position adjustment due to exchange.

Title: Voltage measuring apparatus
Inventor: NAKAMURA TAKUYA
IPC: G01R31/302
Filed: 1993-10-20
Abstract: PURPOSE:To provide a voltage measuring apparatus for accurately detecting change in voltage in local parts of an object to be measured. CONSTITUTION:Light emitted from a first emitting end face 22a of a-laser light source 22 diffuses in an electro-optic member 21 and is reflected on a curved face 21a with a high reflection coat formed on it. Since the center of radius of curvature of the curved face 21a of the eiectro-optic member 21 and a light emitting point on the first emitting end face 22a of the laser light source 22 coincide with each other, a large amount of the reflected light is collected at this light emitting point and is made incident on the laser light source 22. The incident light reaches a second emitting end face 22b of the laser light source 22 and is reflected by a reflecting means. As a result, laser oscillation occurs between the curved face 21a and the reflecting means, and it transmits through the reflecting means for outputting laser light.

CONSTITUTION:A plurality of heat radiating fins 8 are projected in the horizontal direction on the outer peripheral surface of a circumferential wall 10 of a cylinder 6 formed in a cylinder block 3. A baffle plate 14 is disposed around the heat radiating fins 8, thus defining a cooling air duct 15 between the plate 14 and the wall 10. Four head fixing bosses 9 are provided at four points outside the cylinder circumferential wall 10. Each leg portion 5a of head bolts 5 is screwed in the boss 9 so that a cylinder head 4 is fixed to the cylinder block 3. Each boss 9 is deviated downward from the upper end 12 of the cylinder circumferential wall 10 to be projected from the outer peripheral surface of the cylinder circumferential wall 10. Consequently, a sufficiently ample ventilation cooling space 16 is formed above the bosses 9, and further, the space 16 is communicated with the cooling duct 15.

Title: Manufacture of ceramic structure
Inventor: KUROKI YOSHIAKI
IPC: G01N27/12
Filed: 1997-09-09
Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a ceramic structure by which it is possible to efficiently form a part with which a material to be joined is not joined, with high precision when joining the material to be joined to a green molded body. SOLUTION: This method for manufacturing a ceramic structure comprises forming a self-adhesive layer on the surface of a green molded body 1 by applying a self-adhesion inductive liquid of such a nature that a binder to be added to the green molded body 1 is dissolved or caused to swell and bring a material to be joined 21 into contact with the surface of the self-adhesive layer under such a state. Thus a joint form is made by jointing the green molded body 1 with the material 21 through the self-adhesive layer. In addition, prior to the application of the self-adhesion inductive liquid, a joint blocking layer 6 made up of a material insoluble or hardly soluble in the self-adhesion inductive liquid is previously formed on some part, of the entire surface of the green molded body 1, where the joining with the material 21 needs to be avoided.  Consequently, the binder is prevented from coming into contact with the self- adhesion inductive liquid, so that the self-adhesion layer is not formed.
